Falcons

I saw this on the news last night.  Go to See It On Tv - ABC Channel 7

This view of Peregrine Falcons is possible because biologists at UC Santa Cruz and Cornell University collaborated in the mid-1970s to restore a nearly extinct Peregrine Falcon population. At the time, two pairs were known in California—none could be found nesting east of the Mississippi River.
Widespread use of the persistent pesticide, DDT, contaminated the environment worldwide resulting in eggshell thinning that decimated the Peregrine population. DDT was banned by the Environmental Protection Agency in 1972. For the next three decades, the U. C. Santa Cruz Predatory Bird Research Group bred falcons in large aviaries, hatched thin-shelled eggs, climbed to the Cliffside nests of these birds, and restored the California population to an estimated 250 pairs—up from just 2 pairs.
We celebrate this extraordinary success story with the falcon nest camera view of wild nature as it unfolds above city streets. We share the story with school students by presenting school assemblies and with the community by engaging the participation of a large network of UC Santa Cruz students and community volunteers who assist with our ongoing baseline research on this species.

Falcon nest cameras and discussion groups are a compelling gateway activity where people can gain an appreciation of nature. Together, the nest cameras and discussion groups provide entertainment, wonder, and learning, about nature through an intimate look at iconic birds. They also put wildlife in the headlines stimulating interest community-wide. The discussion group is moderated by a university professor who is also an experienced field biologist specializing in birds of prey. Many teachers use the cameras and discussion groups as teaching tools.
